Thanks for the info. The more I researched it, the more I decided against tapping the power from the stock headlight connector. I downloaded a copy of the camry hybrid service manual to see how I can pull a wire (18gauge) all the way to the battery. I'm new to reading the service manuals, but it looks like perhaps I can run a wire beneath the scuff plate either on the drivers or passenger side.
I guess I'll be disassembling my TCH over the weekend. Let me know what you end up doing in case you find an easier way to run a wire to the battery
